I wouldn't say the files claim to be something -- it's the `file´ 
programme that says so, according to some rules in `magic´ files. UTF-8 
contents usually cannot be distinguished from other contents -- a byte 
is a byte is a byte. Some UTF-8 files contain a marker by which one can 
determine, that it's UTF-8. Other markers state that the text is 
written right to left with a citation left to right. Could be Eclipse 
writes such a marker ...

Yes. I Usually revert buffer from file with new encoding, C-x RET r 
<encoding> RET and save the file in that encoding. I'd say it works 
reliably!

I don't know and use Eclipse. Test is with its own documentation -- and 
some reliably encoded files!
